NAEP Analysis and Scaling → Scale Linking and Transformation to the Reporting Metric → Transformation Constants for NAEP Assessments → Coefficients of Linear Transformations of the Content-Strand Scales from the Calibrating Scale Units to the Units of the Reporting Scale, Mathematics Combined National and State Assessments, By Grade: 2011

NAEP Technical DocumentationCoefficients of linear transformations of the content-strand scales from the calibrating scale units to the units of the reporting scale, mathematics combined national and state assessments, by scale and grade: 2011

Grade	Scale	A	B
NOTE: For 2011, grade 12 mathematics was not assessed. Transformed scale scores below 0 were reset to values of 0, and any transformed scale scores greater than 500 were set to values of 500.
